6.5. Definition of Color Appearance
R,G,B and W are defined by (x, y) on the IE chromaticity diagram
NTSC=area of RGB triangle/area of NTSC triangleX100%
Measuring picture: Red, Green, Blue and White (Measuring machine: BM-7)
6.6. Definition of Surface Luminance, Uniformity and Transmittance
Using the transmissive mode measurement approach, measure the white screen luminance of
the display panel and backlight.
6.6.1. Surface Luminance: L
V
= average (L
